In Worcester County Massachusetts a friend received a shipment of over 100 3# packages in April and allin good condition. It just about filled the little post office where he lives and it all went well. They had been advised and were ready. The important thing is that the colonies were locked together and about 6 inches apart on wooden strips.No way that you cut off air. It is important that the shipper, the Postal Service and the receiver keep in good communication and that all take reasonable precautions.
